3 Claims.

My invention relates to an improved method of invisibly setting precious stones and other jewelry and is characterized by the use of a metal cup-like member provided with two or more oppositely disposed grips or tongues of which one at least is resilient and which engage in grooves, recesses or the like formed in the gem or stone beneath its head or widest part.

The cup-like member is applied to the mountings for gems and jewelry by soldering or welding the same to such mountings. This soldering is efiected on the upper side of the mounting of the jewel and has sometimes an objection which is obviated in a further feature of the invention which consists in adding to the lower edge of the cup-like member, a neck, flange or the like by reason of which it is possible to securethis cuplike member with its stone, on the mounting of the jewelry by engaging the said flange in a hole provided in this mounting and riveting it therein.

The invention is illustrated by way of example in the accompanying drawing in which:

, Figure 1 is a plan of the construction of the cup according to the invention with the stone itself removed; Fig. 2 is a cross section of the cup showing a stone in. position; and Fig. 3 is an end view of same; Fig. 4 is a cross section of the cuplike member and its stone in a further form of construction; and Fig. 5 shows an end view corre- 30 sponding to Fig. 4.

This new method of setting is carried into effect according to Figs. 1 to 3 by mounting a stone l in a metal cup-like member 2 which latter comprises within its upper edge, a tongue, spur, grip, clamp or the like 3 adaptedto engage in a corresponding recess, groove, notch or the like 4 formed in the stone as stated hereinabove.

On that part of its periphery opposite to the claw or the like 3, the cup-like member 2 is open and the gap thus formed is filled by a thin strip or strips 5-6 which over a portion 5 of its length, towards the base, is soldered to the corresponding edges of the cup or cap. These soldered parts stop at the small holes I which are made for the purpose of limiting them strictly, and above, that is to say near the recessed edge of the cup'2, the said thin strip remains free in such a manner that it forms a semi-flexible tongue or the like 6 at the free end of which is formed, internally, a

the like 6, it will sufiice, after having engaged the stationary tongue 3 in the recess 4 of the stone by holding it in a slightly inclined position, to lower that on the other side by moving the tongue 6 away, by its resiliency, until the nose 8 of the latterdrops into the recess 9 of the stone. The tongue 6, then being released, re-assumes its initial position, the nose 8 engaging in the recess 9 of the stone. It is thereafter possible to ensure the tightening action on thestone by causing a pressure on the tongue 6 by a special tool.

The stone is thus securely set without any part of its exposed and visible external surface being hidden by metal parts, the setting being thus completely invisible.

According to the construction shown in Figs. 4 and 5 the cup-like member 2 is in addition provided, at its base with a neck, flange, collar or the like it extending over the whole periphery and which is engaged in a hole provided for this purpose in the body H of the jewel which can thus be riveted at [2 on the other side.

Instead of riveting, the connection could be ensured by enlarging the collar ill in its housing or again by soldering the rim of the collar.

The collar Ill need not be continued over the Whole surface of the cup-line member; it could be cut or slit at several places along its surface. It might have several claws or the like which would be secured in the body of the jewel by riveting or soldering as explained hereinabove.

I claim:

1. Means for setting precious stones and other jewelry comprising a cup to receive the stone, recesses in the stone, a rigid tongue on one side of the cup, a resilient tongue on the other side of the cup adapted to spring into the other recess in the stone and means for fixing said resilient tongue in position. 2. Means for setting precious stones and other jewelry comprising a cup to receive the stone, recesses in the stone, a rigid tongue on one edge of the cup engaging one recess in the stone, a gap in the other side of the cup, a strip member filling in said gap, means for resiliently fixing said strip member, a tongue carried by said strip member springing into the other recess of the stone, and means for limiting movement of said strip member.

3. Means for setting precious stones and other jewelry as claimed in claim 1 including a neck for the cup, a hole in the base of the cup to receive said neck which passes therethrough and means for fixing said neck to said cup.
